SPECIFICATION forming part of Letters Patent No. 398,644, dated February 26, 1889.

Application led Iuly 12, 1886.

To @ZZ whom it may concern.-

Be it known that .LCHARLES Il. MOORE, a citizen of the lnited States, residing at Yonkers, in the county ot 1ifestchestcr and State of New York, have invented a new and uset'ul Improvement: in Bath-rlubs, otl which the l"ollowing is a specification.

Previous to my invention bath-tubs have been variously constructed, and traps and overflow-pipes ot' many ditterent designs have been connected thereto in a variety of ways. The commonest construction and arrangement is one in which a circular opening is made in the bottom of the tub and its lining for the reception of a plug-socket and the upper end of a discharge or waste pipe, which latter is formed or provided with some sort ot' trap in proximity to and beneath the tub-bottom, and in which a circular opening is formed in the upper portion ot" one end of the tub for the introduction of one end of an overliowpipe, whose other end exten ds down and connects to the waste-pipe of the trap therein; but it is also common to bring the trap underneath the tub and connect one end of it directly to the circular opening made in the bottom ot" the tub and the other end to the waste-pipe which runs to the sewer-connections, and in this construction it is common to extend the overtiow-pipe from the opening in the end of the tub down directly to the trap.

My invention has for its main objects to improve the construction ot' bath-tubs and the traps used in conjunction therewith, and to so connect and arrange the parts as to simplify and cheapen the structure as an entirety and secure at the same time many important advantages; and to these ends my invention consists in the several features of construction and combinations or arrangements of parts hereinafter more fully described, and particularly pointed. ont in the appended claims.

ln the accompanyin g drawinojs, forming a part of this specilication, Figure l is a vertical central section of abath-tu b and trap involving my invention. lg. L is a horizontal section taken at the line A A, Fig. l. Fig. 3

shows in plan and section a modification of my invention, in which the trap is represented as bolted to the bottoni of an earthenware Serial No. 207,764. (No niotleld i pipe; 3, the top plate or upper surface of the trap; l, the plug` or stopper; 5, a combined plug-socket and trap-screw: ti. the partition of the trap; 7, the solder joint connectingT the trap to the lining; S, a bent portion ot' the overiio\\'pipc; 5l, the liront oll the strainer;

l0, a flange cast on the trap: ll, the outgo or discharge end ol the trap; 12, lugs for supporting the trap: 13, a strainer at the upper end of the overIlow-pipe; il, a gasket; l5, a screw-coupling; lo, a chain holder or support, and lT thebowl oi' the trap.

The bowl of the trap is constructed to contain water, as usual, and its outgo or discharge end is preferably made cylindrical for connection with the customai waste-pipe. From the outgo to the opposite curved extremity the trap-top is made flat. for a purpose that will presently appear.

The bottom of the bath-tub is tormcd with a U-shaped opening or cut-out for the reception of a portion of the `[iat top plate of the trap, and in the construction shown in lig. i. the lining of t-hc bottom of the tub is formed. with a similar coincident opening.

ln connecting the metallic trap to the tub its upper portion is introduced into the U- shaped opening in the tubs bottom until its top plate comes about flush with the internal bottom of the tub and iills said opening, as illustrated. The trap then securcdin place by soldering it to the metal liningof the tub, and its top tlat surface becomes a section or portion of the tubs bottom and serves to strengthen the same. In the top plate of trap thus forming a section of the tulrbottom an aperture is made forthe escape otl water from the tub, and this aperture is threaded to rcceive the combined plug-socket and trapscrew The fiat top plate ot the trap preferably extends beyond the cnd oi the tub, as shown, and is formed with an opening `for the accommodati on of the lower end of the overt] ow-pipe 2, which is formed with a bend, 8, at its upperportion, that extends into the tub.

IOO

The end wall of the tub is formed with a semicireular longitudinal groove, into which about one-half of the overtlow-pipe is fitted.

The strainer or cover 13 is provided with a neck or extension which passes into the upper open bent end of the overflow-pipe, and is held in place by a screw-bolt, 16, which passes through a perforation in the front of the overow-pipe and engages with a threaded hole in the neck or extension. To the bolt lli is attached-one end of a chain, the other end of which is connected with ille stopper or plug 4.

The end wall of the tub extends down to the top of the trap, and the liningthereof is soldered to the lining of the bottom ot' the tub and to the trap and assisisin suppori ing the latter.

By bringii'ig the top of the trap up into the tub and making it form a portion of the bottom of the tub I am enabled to use a device which serves as a plug-socket and a trapscrew instead of providing separa-te devices, as heretofore. In the previous constructions of bath-tubs the plug-sockets were always made immovable and the trap-screws located beneath the floor of the tub.

By combining in one the plugsocket and trap-screw the device may be readily removed from the trap when it is desired to clean the latter bysimply unscrewing it from the inside of the tub. Heretofore, in order to clean the trap when connected beneath the tub, it has been necessary to remove the wooden casing of the tub to remove the ltrap-screw. lAnotherimportant advantage in having the trapserew removable from the inside of the tub is that the iilth and water of the trap cannot escape onto the floor of the room or run down on the ceiling of the door below, as it can in those constructions where the trap-screw is located outside of the tub and below the water-line of the trap.

The lower end of the combined plug-socket and trap-screw preferably extends down into the standingwater of the trap to prevent any circulation of foul air through the overflowpipe when the plug 4 is rout of the socket.

By grooving the end wall of the tub, as show-n and described, the overiiow-pipe can be brought nearer the inside of the tub, so that a swab may be readily inserted to clean its interior; and by this construction and arrangement I am enabled to make the trap shorter and of less weight, besides economzing in space at the end of the tub.

The trap is prevented from being forced n p into the tub by means of lugs or ears l2,cast on the trap and secured to the under side of the tub. These lugs or ears also assist in supporting the trap.

At Fig. 3 the trap is shown provided with a flange, 10, by which, through the medium ol' screws or bolts, the trap maybe secured to an earthenware tub.

AAt Fig. 4 a construction is shown in which the trap and the combined plug-socket and trap-screw are adapted for use in connection with an iron tub, a coupling, 1 5, threaded interior-ly and exteriorly, being used for the purpose. Preferably a gasket is introduced between the tub and the trap.

Vhat I claim as my invention, and desi-re to secure by Letters Patent, is-,

l.. The combination of a traphaving a fiat top with abath-tub bottom having` a U -shaped opening and a metal lining having a similar opening, the said trap being' soldered to the said lining and so supported thereby that its flat top `fills said U-shaped opening Hush with the bottom of the tub and forms a section or portion of said bottom, as set forth.

2. The combination of a trap having a flat top provided with a threaded opening and a threaded plug-socket, with abath-tub bottom having a U-shaped opening and a metal lining having a similar opening, the said trap being soldered to and supported by said lining, so that its flat top lills said opening and forms a section or portion of the said tub-bottom, and the said plug-socket being removable from the inside of the tub (for the pur- C, H.
